Abstract

In this paper the author presents some aspects about the motion of a heavy machine with tires in moving on the irregular roads. Based on the spatial 3-DOF model of machine it was evaluated all eigen pulsations and simulated the tire-road interaction only for the vertical motion of a wheel loader. The influence of the tire characteristics to the dynamic behavior of the loader was studied.
